A is a. vessel, which may he mede of' ordinary tin'ned plete or other snitahle materiel, and to one end ci' ve'hich is ttedra cork or plug, B, secured to a plate, at, having an eye, to which is secured a oord or chain, C. The vessel Aie closedjat the opposite end, with the exception of one er more openings, through which pees strands of fibrous material, the latter being in contact with a sponge, E, which is secured to the lower, end ci thevessel, in the present instance, by wrapping a portion of the sponge to the seme, end over a flange, e. The vessel A is iilled or partly filled with water, and may he connected hy the cord C to an ordinary school-slate. The :vater in the Vessel is conducted by the fibrous strands d to the sponge, which, without being overcharged with water, always remains in the moist condition necessary for an available slate-wiper, for wetting the pages' of letter-copying hooks, for wiping pens, and-for other purposes.

The vessel may he madeof ruhher, or other material, which will yield under pressure, and permit the water to he forced into the sponge, and for the lattel'rnay he substituted a mass oi fibrous strands. In the modification shown in tig. 4, the vessel A is closed at the upper end, the lower end being screwed into a socket, between which and the open end of the vesselintervenes a suitable packing-washer. The lirons strands, in this cese, pass through perforetions at the bottom of the socket.
